Scout, welcome to the BOC, first of all. About the drift socks, I know some of the posters are more familiar than I with exactly what works best, but usually they are designed for a particular size range boat, and I tend to go with one size larger. Right now I use a model from Cabela's, but it was for a smaller boat, and in stiff wind is not enough for the 17' I have now. At this time, I use only the one with a bridle arrangement that tracks the boat with stern to the wind and it works pretty well, unfortunately, it doesn't allow a very wide path of coverage. I really need to purchase another and use two, as you mentioned. That does allow more area coverage. The larger socks also allow much slower drifting, which works better by keeping the bait in an area a little longer.
I hope this will help you some; I'm sure someone else will provide more detailed information later.
